I remember when the stiching on my practice quilt was looking good. So I started on the real quilt and it was like I never sewed a stich in my life.
I figured out I was so nervous that I would mess up that I did. At first was going way to slow then got a little faster. Also noticed the certain motions were easy to do then other and iI would speed up on a certin design turn.
The thing you need most to remember is find a comfortable pace for youself and practice practice practice Enjoy and go with the flow on free motion don't fight it
